Y LATHER-BRUSH FOR POVDERED SOAP.

Application filed September 5, 1919.

To @ZZ whom t may concern.'

Be it known that I, FRANK MCLAUGHLIN,

.a citizen of the United States, residing at 2325 N. 33rd street,Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented a certain new and useful Lather-Brush for Powdered Soap,of which the following is a specification.

My invention relates to lather brushes which are intended for usepreparatory to shaving.

The purpose of this invention is'to provide a narrow opening extendingdeeply into the brush which will receive and to some extent act as ameasure for the quantity of soap powder which it is intended to use andfrom which the soap will not spillV readily but will be distributedthroughout the brush.

A further purpose is to provide a brush and receptacle handle withcoacting retaining parts withinv the receptacle and withV quick andhandy release mechanism therefor capable of operation by the handholding the receptacle handle.

A further purpose is to secure the brush in position by a catch andprovide laterallymovable release operating mechanism, convenient for useby the hand holding the receptacle handle.

A further purpose is to provide a brush and soap-powder-holdingreceptacle-handle having a large front opening normally closed by aremovable brush, which handle is readily cleaned and which issubstantially free from lodging places for dirt and vermin.

A further purpose is to provide for quick drying and ready cleansing ofa lather brush.

Further purposes wilt appear in the specification and in the claims.

It has been thought best to illustrate this invention by severaldiii'erent forms of brush-holding mechanism characterized by snap orlatch holdingdevices within the re- Y ceptacle handle and all but one bylateral movement of the finger contacts of the release mechanism; thoughit is recognized that other forms of operation will come within thebroader claims of this application, and that many other modilicationssecuring lateral movement of the finger contacts will Vbe suggested tothe'designer by the forms shown. The selected forms have been chosenfrom a large number because Specification of Letters Patent.

Comparatively little difficulty has been met in adapting brushes andbrush handles for the use of a fluid or plastic soap, but their weightis against them and it has been found difcult to clean them properlywithout unduly wasting the reserve supply of soap. However, quick, easy,convenient and cleanly application of a powdered soap to handlecontainer and removable brush use have presented greater difficulty butare attained in the various forms disclosed herein.

Taking up first the form shown in Figs. 1-11:`

I provide the brush 2O with a hollow center as shown at 21 extendingclear to the base of the brush to give access for cleaning the brush andlight and air for drying it and keeping it clean. The opening mayconveniently be made of such size as to hold a reasonable charge orquantity for the lather required for a shave.

The open center protects against vermin which seek the dark, damp partsof the brush and fatten on the soap which too often lodges there. l

The bristles are held in the annular groove between the sides 22, 23 ofa holder 24, closed at the center at 25 and flanged at26, to close theopen end of the container handle 27.

Whether the interior wall 22 of the bristle-holding brush socket shallbe straight, as in Fig. 1, or must be tapered, as 24 in Fig.

' 1il to give the center Aopening will depend `upon-the character ofbristles used. The

method of retention also willvary, some being set in rubber; someclamped, as between the inner flange 24 and an edge, such as 28 upon theouter flange,'etc.

Upon the interior of the brush holder'is secured a plug 29, terminatingin a ball or other projection 30. It may be held frictionally orsweated'in (as in Fig. 1) or may beprovided with projections 31 limitingits movement and retained by a screw 32 (as Vin Fig. 1a) or by any othersuitable means.

In'the form of Fig. 12L the 'head may be tapered tospread or to assistin spreading the inner iiange, to spread the bristles more at 21.

At lthe rear end, the container handle is terminated by a base flange 34upon which the brush is adapted to stand, and is sealed Y by a closure35. This is held in position. by

one or more bayonet joints 35 Where the `base of the brush and thesocket into which it fits in the open end of the handle, arecylindricahit is quite desir- 'able that the'sides'do not come intocontact throughout much of the circumference because of sticking fromthe soap powder. I therefore prefer to have ribs 33 of contact Ionly,'as in Figs. 4 and 7 and may use the The support 36 iscircumferentially cut at 38 and the cut parts are turned inwardly intheform of ears 39, whichare apertured at 40 to receive lateralpivotalprojections 41 upon gripping arms 42. These are provided v`withfingers'43 at their forward ends for engagement with and retentionl ofthe ball 30, and `with'apertures 44 at the .reverse ends to pass aV rod45./ A Y Y .The rod carries a spacing ,compressionV i spring .46,tendingto separate the ends 47 of these fingers, andV tubular finger-pressedplungers 48 whose ends 482 are intended to engage with'the outersurfaces of the ends of the gripping arms.

`The space within the receptacle is filled with powdered soap and eachtime that the brush. set .down upon` .the Y `base, 34, this soap issettled to the rear of the container handle.

In operation The brush is moistened and its handle is held in one hand,say the right hand with the forefinger and thumb engaging and pressingthe ends of the iinger contact members 48. This releases the catchesfrom the ball 30. At the same time the brush end, now free, is withdrawnby the left hand from its seat in the end of the handle and is turneduntil Vthe bristles eX- tend in an upward direction. A quantity of soappowder is then poured from the container handle, filling the opening inthe brush. liththe open end of the receptacle directed upwardly, thebrush is now inserted in position and is put into place, as in Fig. 1,the finger-pressed members 48 being pushed together to open the catches,while the brush is inserted. The brush isthen ready to be applied inproducing a lather.

In the form shown in Fig.V 11 the parts are similar except for thesupporting sleeve and the'catch mechanism by which the ball terminal ofthe brush is held.

The pivoted catch parts v are supported upon a frame 49 instead of uponarms inwardly projected from the sleeve 36. The catch members 42Y areprovidedwith apertured pivotal ears 50 bent infrom the sides and withcuppedterminals at 51,*gripping the ball.. Thespring 46surrounds theYpin 45 and is of torsional form with the rsame effect, in that itopposes release of the catch members when the. finger contacts 48l arepressed. l j l Y i ln the form shown in Fig. 12 the sleeve 36 supportsleaf springs 52 embodying the functions ofthe armsand the springs andwhose ends 53 spring outwardly into an inwardly-directed flange 54carried by the base of the brush member. The springY catches arereleased by laterally (radially) movable pins 55 secured Vto the springsat one end and carrying heads 56 at the other.

In theform shown in Figs. 13 and 14, the rearv end of the sleeve 36supports a transverse strip 57, which maybe integral with it as shown,and from whose edges ears 58 are turned. Pins 59 in these ears formpintles` for thejarms 42? pressed apart by' spring 462 so that theirends 53 engage anV inwardly turned flange 54. i

In the form shown in Figs. 15,16 and16a,

Y the finger contacts 48 terminate at their inner ends in annular,reversely-turned cups 60, whose hubs 61 extendradially for engagementbythe' fingers. The hubs are bored to receive a pin l62 aboutJwhichsprings 46? ts, and are counterboredY atx634 for screws Y 64,l fittinginto the lpin and against the hub; Each of the cups engages with aninwardly-turned prong 54 and can.

be,V released ,from it by pressing the rfinger contacts toward eachotheras in the other` figures.

Because the fastening device requires thatthe brush be placed in aparticular position, to bring the prongs in line with the cups, thebrush base and receptacle seat thereforv at the end of the holder arekeyed, as shown at in Figs.` 1G and 16a.V f

In the form shown in Fig. 18, the clamping devices or catches 52', areformed of spring material and are terminated b anges 66, such that bypressure the ball can be forced between them and they will snap over it.The ball can also be pulled out from between them when it is desired towithdraw the brush.

In the form shown in Fig. 18, a single linger contact 67 is apertured toslide upon a pin 45 against compression spring 464. It carries a prong43 to pass through an opening in a strip 29 secured to the back of thebrush.

In either case the finger contact is fiattened and is guided againstturning by the walls of the container through which it passes.

In the prong form the back of the brush and the container are keyed topresent the opening in the strip. The prong is tapered to tighten thebrush within the handle.

It will be evident that the catch or fastener is protected within thecontainer in all of the forms and lies back of the zone of engagement ofthe brush base with the mouth of the container, so that any tiltingpressure against the brush or brush base will be resisted bythe catchacting through the leverage which this rearward position of the catchprovides.
